BOBBIN-WINDING MACHINE.

Application led December 27, 1923.

This invention relates to bobbin winding machines, and more particularly to a machine for winding material on an arcuate shaped bobbin.

, An object of this invention is to construct a winding machine which is adapted to wind strand material on an arcuate shaped object or bobbin.

Another object of this invention is to oonstruct a bobbin winding machine in which the distributing means is stationary duringv the winding operation, means being provided for reciprocating the bobbin back and forth asthe material is applied thereon.

A further object of this invention is to construct a bobbin winding machine which is comparatively simple in its oper-ation and which occupies a relatively small amount of floor space.

Other objects and advantages of the present invention will more fully appear from the following description and will be particularly pointed out in the appended claims.

In the accompanying` drawings,

Fig. 1 is a longitudinal section through the center of a bobbin winding machine embodying the present invention;

Fig. 2 is a front elevation of the mechanism4 shown in Fig. 1;

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1 and looking in the direction of the arrows, and

Fig. 4 is a fragmentary detail view of an arcuate shaped bobbin with the material wound thereon. v

The mechanism of the machine is mounted within a housing or hollow casting 10, having a removable plate 11 covering an opening in one of its sides so that all parts may be readily assembled and the necessary mechanisms very easily substituted when it is desired to change from one type of wind-- ing to another.

A driving shaft 12 is journaled in bear ings 13 and 14 and has keyed thereto a bevel gear 15 which meshes with a bevel gear 16 keyed toa vertical shaft 17 journaled in lateral extending members 18 and 19 of the frame 10. A flier or distributor comprising a cylindrical hollow casting 2O is suitably mounted on the upper end of the vertical shaft 17 so that it is rotatable therewith,

therefrom and passed over guide rollers 23 anc 24 which are positioned on the periphery of said distributor and serve to pass the winding' material from the supply reel 22 toa distributing roller25 mounted near an opening 2G in the top of the distributor 20. I

T he arcuate shaped bobbin 27 to be wound is rigidly held in one end of an arm 28 which is pivoted at 29 to an upwardly eX- tending bracket 30 mounted on the main frame 10. rlhe other end of the arm 28 is pivoted to a' link 31 which in turn is pivoted to the upper end of a vertical bar 32.

The mechanisms employed to reciprocate lthe bobbin 27 as the strand material is applied thereon will now be described.

A bevel gear 35 is keyed to the driving shaft 12 and meshes with a bevel gear 36 keyed to a vertical shaft 37 journaled in bearings 38 and 39 .formed in the frame 10.

A bushing 40 is also keyed to the shaft 37 l and its outer surface is machined to form an endless screw thread. A follower 41 rides loosely on the bushing 40 and carries a dog 42 which tits into the endless thread thereof.

Adjustable stops 43 and 44 are'positioned at predetermined points on the bushing 40 and serve to .reverse the direction and limit the distance oftravel of the follower 41. An arm 45 is formed integral with the follower 41 and rides loosely on a vertical guide rod 46, the upper end of which is supported in a bearing 47 formed in the frame 10, and its lower end is rigidly held in a bracket 48 which is carried by the shaft 37. The follower arm 45 is rigidly fastened to the lower end of the bar 32 by a screw 49 which may be received in either of a plurality of holes`50 in the bar 32. The holes 50 provide a means for varying the feeding region on the object or bobbin to be wound.

Any suitable source of power (not shown) is applied to the driving shaft 12 which operates in conjunction with bevel gears 15 and 16 to revolve the distributor 20. At the same time bevel gear 35 which is keyed te the shaft 12 operates in conjunction with bevel gear 35 to revolve the reversible screw thread bushing 40, causing the follower t1 to reciprocate back and forth between the stops 4:3 and 44 in a well known manner. The reciprocating motion of the. follower 4-,0 is transmitted to the arcuate shaped bobbin 2T through the follower arm 45, bar 32, link 31, and lever arm 28 as clearly shown in Fig. 1. The distributing'roller 25 revolves with the distributor 2O about the bob bin 2? and in so doing distributes the strand material on said bobbin as it is drawn from the supply recl 22 over the guide rollers 23 and 2st- Then it is desired to change from one type of winding to another.A gears of the required ratio are substituted for the bevel gears 1.5 and 16, thereby changing the revolvingr speed of the distributor 20. Liliewise, the ratio between bevel gears 35 and 36 may be changed so as to obtain the desired reciprocating motionin the bobbin 27.

That is claimed is:

1. In combination, means for passing strand material around an arcuate-shaped object, means, for supportingthe object at one end, a revolving distributor, and means for reciprocating said object in an arcuate path relativeto said distributor.

In combination, means for passing strand material around an arcuate-shaped objecta revolving distributor, a supply reel revolvably mounted within said distributor at an angle to the perpendicular. axis thereof.

3. In combination, means for passing strand material around an arcuate-shaped object, a, revolving distributor, a supply reel revolvably mounted at an angle tov the rotating aXis of sai d. distributor to permit the material to be. freely withdrawn therefrom, and means for passing the strand material from. said supply reel to said arcuate-shaped object.

4:. In combination, means for passing strandy material around an arcuate-shaped object, a. revolving distributor, a supply reel revolvably mounted withinsaid distributor at an angle to the axis of rotation thereof to permit the material to be freely withdrawn therefrom, and means for reciprocating said arcuate-shaped object relative to said distributor as the material is applied thereon.

5. In a machine for winding material around an arcuate-shaped bobbin having one free end, a distributor, and means for reciprocating said bobbin relative to said distributor.

6. In a machine for winding material around an arcuate-shaped bobbin having one free end, adistributor, an opening in said distributor, and means for reciprocating the bobbin within said opening.

7. In a machine for winding material around an arcuate-shaped bobbin having one free end, revolving distributor, an opening in said distributor, and means for reciprocating said bobbin in an arcuate path within said opening.

8. In a machine for winding material around an arcuate-shaped bobbin having one free end, a distributor, a supply reel revolvably mounted within said distributor at an angle to the perpendicular axis thereof, means for automatically reciprocating said bobbin relative to saiddistributor, and means for distributing the strand material evenly upon said bobbin.

9. In a machine for winding st 1and material around an arcuate shaped bobbin, means for supporting the object at one end, a distributor` and means for moving the opposite end of the object in an arcuate path towards and away from said distributor.

10. In av machine for winding strand niaterial around an arcuate shaped bobbin supported at one end and free at the opposite end, a distributor having an opening therein, and means for reciprocating the free end ofthe bobbin in an arcuate path within said opening,

In witness whereof, I hereunto subscribe my name this'lS day of December A. D., 1923.
